What’s the difference on OBC and OBN Seismic Exploration?

obc4dAt present all countries have shifted the focus of oil and gas exploration to Ocean. As the main means of oil exploration in shallow sea areas, OBC (Ocean Bottom Cable) seismic explorationABSTRACT Time-lapse 4D full-waveform inversion (FWI) is a valuable technology for hh-resolution imaging of reservoir changes caused by hydrocarbon production and storage.
